## Discovery
Generated instructions contain a tool catalog with a default budget of 2,000 estimated tokens. Configure it with
`discovery: { catalogBudget }`. Every namespace remains visible, and the instructions say whether the catalog is
complete or partial.
`runtime.catalog()` returns structured descriptors — exact path, description, and generated TypeScript signature — for
every visible tool. Hosts render their own model-facing instructions from these descriptors; `CodeMode.searchSignature`
and `CodeMode.toolExpression(path)` supply the exact callable forms.
The synchronous `search(...)` built-in is always available and advertised when the catalog is partial. It supports
exact-path lookup, namespace-scoped search, empty-query browsing, and pagination, and returns callable paths with full
signatures. Search counts toward `maxToolCalls`.
